In 1854 a colonization convention was held in Cleveland for those who were interested in emigration within the boundaries of the western hemisphere. The convention noted that the Afro-American community was developing a growing sense of racial consciousness and pride. Although blacks were in the minority in Europe and America, it pointed out that most of the world's population was colored. Integration into the mainstream of American life, besides appearing to be impossible, seemed to demand the denial of selfhood for the black man. Therefore, black separatism grew in popularity and became a platform from which to maintain a sense of identity and individual worth. However, many militants like Frederick Douglass did not approve of black nationalism and colonization. They claimed that they were still Americans and did not constitute a separate nation. Leaders who were not black nationalists, however, could still be militant. Although Douglass did not actively support John Brown's raid on Harpers Ferry, the reason for his decision was that he doubted its effectiveness and not because he opposed its violent technique. In fact, Douglass applauded the attack. He said that Brown had attacked slavery "with the weapons precisely adapted to bring it to the death," and he contended that, since slavery existed by "brute force," then it was legitimate to turn its own weapons against it. Previously the Reverend Moses Dixon had established two fraternal organizations to train blacks for military action. Although nothing substantial came from them, the idea of developing guerrilla forces as the only remaining tool against slavery was gaining support. Another militant, H. Ford Douglass, concluded that the government had become so tyrannical that it was possible for him to engage in military action against it without his becoming a traitor to his country. He said, "I can hate this government without becoming disloyal because it has stricken down my manhood, and treated me as a salable commodity. I can join a foreign enemy and fight against it, without being a traitor, because it treats me as an ALIEN and a STRANGER, and I am free to avow that should such a contingency arise I should not hesitate to take any advantage in order to procure such indemnity for the future." Robert Purvis, a Philadelphian, also agreed that revolution might be the only tool left with which to secure redress for grievances. He contended that to support the government and the constitution on which it was based was to endorse a despotic state, and he went on to express his abhorrence for the system which destroyed him and his people. Purvis said that he could welcome the overthrow of this government and he could hope that it would be replaced by a better one.
